WHAT IS DAHUA STARLIGHT CAMERAS?

by admin

Night Color technology works differently than the technology used in Starlight cameras. Cameras that incorporate Night Color technology use a high-performance sensor and ISP, and an achromatic large aperture lens, to produce crisp, clear color images in low-light environments. This light-sensitive technology allows the camera to remain in Color Mode and to capture more available light to reproduce color images with superior detail and contrast in applications with at least 1 lux of ambient or artificial light.

Unlike Starlight Technology, Night Color Technology does not utilize an IR Cut filter. This results in an image that remains in color 24/7 without switching to black/white. Night color also utilizes an Achromatic lens. This type of lens is a combination of concave and convex pieces of glass that focuses the different color wavelengths of light into a single plane. An Achromatic lens eliminates the problematic chromatic aberrations and is the most cost-efficient means for good polychromatic imaging. Dahua Night Color cameras also have an f-stop of 1.0 on 2MP models or 1.2 on the 4MP models to deliver crisper and clearer full-color images in all environments with at least 1 lux of ambient light.

Similar to Starlight Technology, Dahua’s Night Color Technology utilizes Back-illuminated CMOS technology.  STARVIS™ sensors offer a set of optical features to balance light throughout the scene, resulting in clear images in dark environments. A back-illuminated structure increases the amount of light that enters each pixel and moves the sensor’s photosensitive surface closer to the light. It also utilizes Smart Image Signal Processing to convert an image into digital form while performing operations that enhance the image or extracts useful information. ISP identifies and corrects imperfections caused by the lens, color filter, or sensor.

Dahua’s Starlight technology generates crystal clear images in near-complete darkness.

Starlight Features

Dahua’s Basic Starlight technology offers good low-light performance for applications with a minimum illumination of 0.008 to 0.009 lux. This option offers a more affordable price for low-light technology that is ideal for moderately dark areas.

Recommended scenarios: parks, stadiums or parking lots with some ambient lighting such as street lights.
